Title: Digital signal extraction circuit
Inventor: WADA YOSHINORI
IPC: H03K5/00
Filed: 1978-07-19
Abstract: PURPOSE: To simplify the circuit constitution by giving a delay to the clock signal and then to the digital signal if other sampling signals are already supplied when the digital signal divided by the divider is extracted.  
     CONSTITUTION: If clock signal CP is supplied to terminal T in the state under which sampling signal SP is supplied to terminal D, D-type FF element F is reset by the rise of signal CP. In addition to such element F, the following units from the extraction circuit: divider D 0  which divides signal CP input 1/2 and delivers the digital signal; inverter I; amplifier A; AND gate AND; resistance R and capacitor C. In such constitution of the circuit, output d 1  of circuit D 0  is used directly to secure the other processes if supplied sampling signal SP 1  does not reach the rise time point of signal CP. However, if SP 3  reaches the rise of CP, output d 3  of circuit D 0  is kept under the set state. Thus output b 3  of gate AMD is delayed, and the division output is delivered after the preceding process is over.

Title: Preparation of semiconductor device
Inventor: SAKAEMORI TAKAHISA
IPC: H01L21/205
Filed: 1985-04-24
Abstract: PURPOSE:To make it possible to manufacture a semiconductor device of high reliability avoiding the generation of cracks and warps, by forming previously a groove in the scribed part of the semiconductor substrate and dispersing the internal stress of the semiconductor film formed on the groove. CONSTITUTION:The concave groove 3 is formed on the scribed part of the semiconductor substrate 1 by etching, and the semiconductor film 2a is formed on the groove. As the shape of the groove is concave, the semiconductor film 2a is continuously formed along the groove, but the chain of molecules constituting the semiconductor film 2a, the source of stress, decreases to the amount corresponding to the fall of the groove, and the stress is reduced. In the case where the groove 4 in the form of an overhang is formed on the scribed part of the semiconductor substrate 1 by etching, and the semiconductor film 2a is formed on the groove, the semiconductor film 2a is divided by the overhang part because of the overhang shape of the groove 4. Consequently, the chain of molecules constituting the semiconductor film 2a is also divided and the stress is still more reduced.
